It's time for another low-effort post listing off the multitude of license plates I noticed last month. It would have been on the high end even without a trip to New York City and Baltimore at the end of the month, but I got a few rare ones added during those travels.
U.S. States: Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Vermont, Virginia, Washington, West Virginia, Wisconsin
Other U.S.: District of Columbia, Puerto Rico, U.S. government
Canada: Manitoba, New Brunswick, Ontario, Quebec
There are nine U.S. states that I didn't see any license plates from in December. I saw one of them on January 1 in a supermarket parking lot and another this morning on my own street.
Missing from previous two months: I saw Montana in November and North Dakota and Utah in October. Those were the only three October and November had that I didn't see in December. So there are six U.S. states that I didn't see in any of the three months I've chronicled so far (although one of them is already in January's list, so there are really only five I haven't seen since I started doing this).
Additions not in previous months: Alabama, Arizona, Arkansas, Kentucky, Nebraska, Nevada, Puerto Rico, US government, Manitoba, New Brunswick
